Channel estimation methods based on pilot signals are commonly used in OFDM systems [3,4], moreover, the pilot channel estimation algorithms are classified into LS channel estimation, maximum likelihood (ML) channel estimation, and minimum mean square error (MMSE) channel estimation [5]. LS ...
In this work, we present a new approach to solving closed-form SR problems (with ground-truth not necessarily known), which combines the popular iterated local search metaheuristic (ILS) [38,39] with the ordinary least square method (OLS) [40]. ILS mostly handles combinatorial (discrete) asp...
R - Nonlinear Least Square - When modeling real world data for regression analysis, we observe that it is rarely the case that the equation of the model is a linear equation giving a linear graph. Most of the time, the equation of the model of real world
In some embodiments, the processor 210 may obtain the artifact calibration coefficient using a polynomial fitting algorithm, a cosine fitting algorithm, a Gaussian fitting algorithm, a least square fitting algorithm, or the like, or any combination thereof. In some embodiments, the processor 210 may...
